A simple device that can capture its own weight in water from fresh air and then release that water when warmed by sunlight could provide a secure new source of drinking water in remote arid regions, new research from KAUST (King Abdullah University of Science & Technology) suggests.
At the heart of the device is the cheap, stable, nontoxic salt, calcium chloride. This deliquescent salt has such a high affinity for water that it will absorb so much vapor from the surrounding air that eventually a pool of liquid forms.
The full research paper is available on-line.

"Death Valley has way more (because it is hotter)."
Show me the numbers. Your "it's hotter" claim ignores hundreds of other factors which affects water density of the air.

It also probably does not average it over the year. Sure, its fucking cold in New York City in December, but it is also 100 degrees in July.
